String Op

The String Op node applies a text transformation to an input string. It supports a wide range of operations, from simple formatting like making text uppercase to more advanced manipulations like find-and-replace and regex patterns. This is your go-to node for any kind of text processing within a flow.

Inputs

Name	Type	Description
Input	string	The text to transform
Arg	string	An argument used by certain operations (e.g., the replacement text for replace, the search term for indexOf)

Outputs

Name	Type	Description
Result	string or number	The transformed result. Most operations return a string, but length and indexOf return a number.

Configuration

• Operation: The transformation to apply. Options:
  • uppercase -- Converts all characters to uppercase
  • lowercase -- Converts all characters to lowercase
  • trim -- Removes whitespace from the beginning and end
  • concat -- Appends the Arg value to the end of the input
  • replace -- Replaces the first occurrence of Arg in the input (use regex replace for advanced patterns)
  • split -- Splits the string by the Arg delimiter and returns an array
  • length -- Returns the number of characters in the input
  • indexOf -- Returns the position of Arg within the input, or -1 if not found
  • slice -- Extracts a portion of the string using Arg as the start and end positions (e.g., "0,5")
  • regex replace -- Replaces text matching a regex pattern defined in Arg

Example

You want to display a viewer's username in all caps in a custom alert. Connect the trigger's username output to the Input handle, set the operation to uppercase, and connect the Result to your alert's display name field. "nightbot" becomes "NIGHTBOT".
